Chlorine → Chloranil

참여 물질

반응 단계

After 146 parts (2.1 mol) of chlorine gas have been introduced over a period of 7.5 hours, a thick, light beige-colored suspension composed predominantly of tetrachlorohydroquinone, is obtained at the temperature level of 95° C. 21 parts of chlorine were found in the off-gas. After a further 84 parts (1.2 mol) of chlorine gas have been introduced over a period of a further 8 hours, a thin, light yellow suspension is obtained at the temperature level of 105° C., from which 106.4 parts of chloranil having a melting point of 255° to 260° C. are isolated under the working-up conditions according to the example. The chloranil still contains significant amounts of mono-, di- and tetra-chlorohydroquinone.
